AW11 Header Design Update

Just a quick update on the SV3Power AW11 header. We took some time to work on equalizing the length of the primary tubes. They’re now all within a 3/4″ spread from shortest to longest. The update means that two of the primary tubes have to be made in two pieces and welded together, but that’s only a little more work, so we’re going forward with it.

In comparison, the original Toyota 20V header had about a 3″ spread from shortest to longest primary!
